Spring Cloud之网关搭建

统一由网关进行拦截判断 

要不放到每个服务里面就很不合适了 冗余

 

主要的:

               <dependency>
			<groupId>org.springframework.cloud</groupId>
			<artifactId>spring-cloud-starter-netflix-zuul</artifactId>
		</dependency>

  

zuul和eureka都是基于netfix里面开源出来的

 

网关有公网ip 其他的服务没有 但是 网关和服务处于局域网内  客户端访问时候经过网关 通过网关去实现

yml:

###注册 中心
eureka:
  client:
    serviceUrl:
      defaultZone: http://localhost:8100/eureka/
server:  ##api网关端口号
  port: 80
###网关名称
spring:   ##网关服务名称
  application:
    name: service-zuul
### 配置网关反向代理    
zuul:
  routes:
    api-member:  ##随便写的  用以区分
     ### 以 /api-member/访问转发到会员服务   通过别名找
      path: /api-member/**
      serviceId: app-toov5-member  ##别名  如果集群的话  默认整合了ribbon 实现轮训 负载均衡
    api-order:   ##随便写的
        ### 以 /api-order/访问转发到订单服务
      path: /api-order/**
      serviceId: app-toov5-order   ##别名

  

启动类:

package com.toov5;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.EnableEurekaClient;
import org.springframework.cloud.netflix.zuul.EnableZuulProxy;

@SpringBootApplication
@EnableEurekaClient
@EnableZuulProxy  //开启网关代理
public class AppGateway {
   public static void main(String[] args) {
   SpringApplication.run(AppGateway.class, args);     
}
}
